First, the contents of the program recording apparatus according to the first embodiment of the present invention will be described. The program recording apparatus according to the first embodiment of the present invention is mounted on a moving body having moving means. Examples of the moving body include vehicles (including four-wheeled vehicles and two-wheeled vehicles). For example, when the moving body is a vehicle, the moving means is realized by each part and each function for the vehicle to travel. At this time, the moving means includes a battery mounted on the vehicle.

  FIG. 1 is a block diagram showing an example of a functional configuration of a program recording apparatus according to Embodiment 1 of the present invention. As shown in FIG. 1, the program recording apparatus according to the first embodiment of the present invention includes a route search unit 101, a keyword generation unit 102, a determination unit 103, a recording unit 104, a time information acquisition unit 105, The weather information acquisition unit 106 and the detection unit 107 are included.

  The route search unit 101 searches for a route to the destination based on the map information. When searching for a route, a route with a high priority is searched based on a setting made in advance by a user or the like. Examples of preset settings include “search for a route that arrives at the destination earlier than a short distance”, “search for a route with priority on a general road (or toll road)”, “width of 6 m or more Search for a route so that it can pass through the road. Information on the route searched by the route search unit 101 or the destination set in the route search is stored in a storage unit (not shown) provided in the program recording device.

  The route searched by the route search unit 101 includes a route re-searched during route guidance in addition to a route searched before the start of route guidance. The re-search is performed when the user intentionally changes the waypoint or the destination in addition to the case where a traffic jam occurs on the route being routed. In many cases, the re-searched route includes the intention of the user. For example, if a route that travels along the sea is searched after a route that travels along the mountain, it is likely that the user wants a route that travels along the sea rather than along the mountain. I can guess that.

  The keyword generation unit 102 generates a keyword from information about the destination or information about the route searched by the route search unit 101. The keyword generation unit 102 may generate a keyword from information related to the destination or information related to the route searched by the route search unit 101 based on the information acquired by the time information acquisition unit 105. The keyword generation unit 102 may generate a keyword from information about the destination or information about the route searched by the route search unit 101 based on the information acquired by the weather information acquisition unit 106.

  The determination unit 103 determines a program to be recorded based on the keyword generated by the keyword generation unit 102. The determination unit 103 can determine, for example, to record a program that includes the keyword generated by the keyword generation unit 102 in the title. The recording unit 104 records the program determined to be recorded by the determination unit 103. The recording unit 104 records a program based on the remaining battery level detected by the detection unit 107. More specifically, the recording unit 104 records a program when the remaining battery level is such that the program can be recorded in consideration of the recording time of the program to be recorded.

  The time information acquisition unit 105 acquires information related to at least one of the date and time when the route was searched or the date and time when the moving means moved along the route. Hereinafter, in the present embodiment, “information regarding at least one of the date and time when the route was searched or the date and time when the moving means moved along the route” will be described as “time information”. For example, the time information acquisition unit 105 may include a dedicated storage unit that stores the date and time each time a route is searched or the moving unit moves the route. In this case, the time information acquisition unit 105 can acquire the time information from the information stored in the dedicated storage unit. Further, the time information acquisition unit 105 may acquire the time information from, for example, information related to the history of the route searched by the route search unit 101.

  The weather information acquisition unit 106 acquires information about the weather when the route is searched or the weather when the moving means moves along the route. Hereinafter, in the present embodiment, “the weather information when the route is searched or the weather information when the moving means moves along the route” will be described as “weather information”. The weather information acquisition unit 106 may include, for example, a dedicated storage unit that stores the weather information at that time each time a route is searched or the moving means moves along the route. In this case, the weather information acquisition unit 106 can acquire the weather information from the information stored in the dedicated storage unit. Further, the weather information acquisition unit 106 appropriately acquires the weather when the route is searched by the route search unit 101 or when the route searched by the route search unit 101 is moved by the moving unit from the outside. It may be. In the present embodiment, the time information acquisition unit 105 and the weather information acquisition unit 106 are involved in keyword generation in the keyword generation unit 102.

  The detection unit 107 detects the remaining battery level in the moving means. Specifically, for example, the detection unit 107 detects a voltage value of a battery mounted on the vehicle. The detection unit 107 may detect the remaining battery level by detecting whether or not the voltage value of the battery is equal to or higher than a predetermined value.

(Processing procedure of the program recording device)
Next, a processing procedure of the program recording apparatus according to the first embodiment of the present invention will be described. FIG. 2 is a flowchart for explaining the processing procedure of the program recording apparatus according to the first embodiment of the present invention. The process shown in FIG. 2 is executed on condition that the route search unit 101 has previously performed a route search. In the process shown in FIG. 2, it is first determined whether or not a predetermined time has come (step S201). The “predetermined time” may be, for example, a fixed time such as 0 o'clock or 6 o'clock, may be a time set in advance by the user, or a predetermined time has elapsed since the previous processing was performed. It may be the time. If it is determined that the predetermined time has not come (step S201: No), the process proceeds to step S210.

  If it is determined that the predetermined time has come (step S201: Yes), the destination or route information (described as destination / route information in FIG. 2) is extracted (step S202). In step S <b> 202, information related to the destination set so far including the present and the route to the destination searched by the route search unit 101 are extracted. The information extracted in step S202 can be extracted from information stored in a storage unit included in the program recording device, for example.

  Next, it is determined whether or not time information is taken into consideration (step S203). The determination as to whether or not to consider the time information may be made based on the setting in the determination unit 103, for example. If it is determined that the time information is considered (step S203: Yes), the time information is acquired (step S204). For example, when a dedicated storage unit for storing time information is provided, the time information is acquired from the storage unit. When there is a history of routes searched by the route search unit 101, time information may be acquired from information related to the history without providing a dedicated storage unit. If it is determined that the time information is not considered (step S203: No), the process proceeds to step S205.

  Next, it is determined whether or not weather information is considered (step S205). The determination as to whether or not to consider the weather information may be made based on the setting in the determination unit 103, for example. If it is determined that the weather information is considered (step S205: Yes), the weather information is acquired (step S206). For example, when a dedicated storage unit for storing weather information is provided, the weather information is acquired from the storage unit. The weather information may be acquired from the outside when it is determined that the weather information is considered without providing a dedicated storage unit. If it is determined that the weather information is not considered (step S205: No), the process proceeds to step S207.

  And a keyword is produced | generated from the information regarding the destination, or the information regarding the path | route searched by the path | route search part 101 (step S207). In step S207, if it is determined in step S203 that time information is considered, keywords are extracted in consideration of time information. Specifically, for example, if “winter” is acquired as time information and the destination is “Naeba”, the keyword “ski” is generated. For example, if “summer” is acquired as time information even if the destination is “Naeba”, the keyword “summer resort” is generated. In addition, for example, when “rain” is acquired as weather information and the destination is “department store”, the keyword “shopping” may be generated.

  Next, a program is determined based on the generated keyword (step S208), and information relating to the determined program is accumulated (step S209). In step S208, for example, it is determined to pre-record a program that includes the keyword generated in step S207 in the title. Specifically, for example, when the keyword “skiing” is generated, a program such as “skiing snowboarding information” is determined to be reserved for recording. The “information about the program” stored in step S209 is information necessary for recording the program, such as a broadcast date, a broadcast time, a broadcast channel, and the like. If it is not determined that the program start time has come (step S210: No), the process returns to step S201.

  If it is determined that the program start time has come (step S210: Yes), it is determined whether or not the remaining battery level is greater than a predetermined value (step S211). In FIG. 2, the process of step S211 is described as “remaining battery amount> predetermined value?”. If it is determined that the remaining battery level is greater than the predetermined value (step S211: Yes), a recording process is performed (step S212). In step S212, the program specified by the information regarding the program stored in step S209 is recorded. If it is determined that the remaining battery level is less than the predetermined value (step S211: No), the process returns to step S201. Even when it is determined in step S211 that the remaining battery level is lower than the predetermined value, the capacity of the battery becomes equal to or higher than a predetermined value that allows recording, for example, when a vehicle equipped with the program recording device travels a long distance. There is also.

  Thus, according to the program recording apparatus of the first embodiment, the keyword is generated from the information related to the destination or the information related to the route to the destination searched based on the map information. A program to be recorded is determined based on the generated keyword. Then, the determined program is recorded. As a result, it is possible to record a program related to the user's action without requiring a complicated operation such as designating in advance the broadcast date, broadcast time, broadcast channel, or keyword of the program to be recorded. As a result, programs that are of interest to the user (or related to those that are of interest) can be recorded without user intervention.

  According to the program recording apparatus of the first embodiment, at the time of recording, information related to at least one of the date and time when the route is searched for, or the date and time when the moving unit moves the route is acquired. . Based on the acquired information, a keyword is generated from information related to the destination or information related to the route. Further, according to the program recording apparatus of the first embodiment, information on the weather when the route is searched or the weather when the moving means moves along the route is acquired. Based on the acquired information, a keyword is generated from information related to the destination or information related to the route. Thus, according to the program recording apparatus of the first embodiment, it is possible to generate a keyword that takes into account time information and weather information. Then, by determining a program to be recorded based on this keyword, it is possible to record a program more relevant to the user's behavior and the memories associated therewith.

FIG. 4 is a flowchart for explaining the processing procedure of the program recording apparatus according to the second embodiment of the present invention. The process shown in FIG. 4 is executed on condition that the route search unit 101 has previously performed a route search. In the process shown in FIG. 4, it is first determined whether or not a predetermined time has come (step S401). The “predetermined time” may be, for example, a fixed time such as 0 o'clock or 6 o'clock, may be a time set in advance by the user, or a predetermined time has elapsed since the previous processing was performed. It may be the time. If it is determined that the predetermined time has not come (step S401: No), the process proceeds to step S410.

  If it is determined that the predetermined time has come (step S401: Yes), the destination or route information (described as destination / route information in FIG. 4) is extracted (step S402). In step S <b> 402, information related to the destination set so far including the present and the route to the destination searched by the route search unit 101 are extracted. The information extracted in step S402 can be extracted from information stored in a storage unit included in the program recording device, for example.

  And a keyword is produced | generated from the information regarding the destination, or the information regarding the path | route searched by the path | route search part 101 (step S403). For example, if the destination is “Tokyo Zoo”, keywords such as “panda”, “koala”, “giraffe”, “lion”, etc., bred at the zoo are generated.

  Subsequently, it is determined whether or not the time information is considered (step S404). Whether or not to consider the time information may be determined based on the setting in the determination unit 103, for example. When it is determined that the time information is considered (step S404: Yes), the time information is acquired (step S405). For example, when a dedicated storage unit for storing the time information is provided, the time information may be acquired from the storage unit. The time information may be acquired from information related to the history of the route searched by the route search unit 101. If it is determined that the time information is not considered (step S404: No), the process proceeds to step S406.

  Subsequently, it is determined whether or not weather information is considered (step S406). Whether or not the weather information is taken into account may be determined based on the setting in the determination unit 103, for example. If it is determined that the weather information is considered (step S406: Yes), the weather information is acquired (step S407). For example, when a dedicated storage unit for storing weather information is provided, the weather information may be acquired from the storage unit. The weather information may be acquired from the outside when it is determined that the weather information is considered. If it is determined that the weather information is not considered (step S406: No), the process proceeds to step S408.

  Then, a program to be recorded is determined based on the keyword generated in step S403 and time information or weather information (step S408). For example, if the keywords "Tokyo Zoo", "Panda", "Koala", "Giraffe", "Lion" are generated, "Latest information of Tokyo Zoo", "Ecology of the lion king of beasts" A program including the keyword in the title is determined as a program to be recorded. Further, information regarding the determined program is accumulated (step S409). The “information about the program” stored in step S409 is information necessary for recording the program, such as a broadcast date, a broadcast time, a broadcast channel, and the like. If it is not determined that the program start time has come (step S410: No), the process returns to step S401. If it is determined that the program start time has come (step S410: Yes), it is determined whether or not the remaining battery level is greater than a predetermined value (step S411). In FIG. 4, the process in step S411 is described as “remaining battery amount> predetermined value?”

  If it is determined that the remaining battery level is greater than the predetermined value (step S411: Yes), a recording process is performed (step S412). In step S412, the program specified by the information related to the program stored in step S409 is recorded. If it is determined that the remaining battery level is less than the predetermined value (step S411: No), the process returns to step S401.

  As described above, according to the program recording apparatus of the second embodiment, the keyword is generated from the information related to the destination or the information related to the route to the destination searched based on the map information. In addition, information related to at least one of the date and time when the route is searched or the date and time when the moving unit moves the route is acquired. Further, according to the program recording apparatus of the second embodiment, information on the weather when the route is searched or the weather when the moving means moves along the route is acquired. Then, a program to be recorded is determined based on the generated keyword and the acquired information.

  As a result, it is possible to record a program related to the user's action without requiring a complicated operation such as designating in advance the broadcast date, broadcast time, broadcast channel, or keyword of the program to be recorded. As a result, programs that are of interest to the user (or related to those that are of interest) can be recorded without user intervention. In addition, it is possible to select and record programs more relevant to user actions and associated memories.

(Hardware configuration of navigation device)
Next, a navigation device according to an embodiment of the present invention will be described. The navigation apparatus of the present embodiment is an example for realizing the program recording apparatus of the present invention. First, the hardware configuration of the navigation device will be described. FIG. 5 is a block diagram showing an example of a hardware configuration of the navigation apparatus according to the embodiment of the present invention.

  In FIG. 5, the navigation apparatus according to the embodiment of the present invention is mounted on a vehicle, and includes a central control unit 501, a user operation unit 502, a display unit 503, a position acquisition unit 504, a recording medium 505, Recording medium decoding unit 506, guidance sound output unit 507, communication unit 508, route search unit 509, route guidance unit 510, guidance sound generation unit 511, speaker 512, recording unit 513, and recording medium 514 And a recording condition storage unit 515 and a database holding unit 516.

The display unit 503 displays icons, cursors, menus, windows, or various information such as characters and images. The display unit 503 displays map information stored in the recording medium 505 and information related to route guidance.

  The position acquisition unit 504 acquires the current position of the own device. Here, the current position of the device itself is obtained by receiving a radio wave from a GPS satellite and obtaining a geometric position with respect to the GPS satellite, and can be measured anywhere on the earth. GPS is an abbreviation for Global Positioning System, and is a system for accurately obtaining a position on the ground by receiving radio waves from four or more satellites. In addition, since it is a well-known technique, description about GPS is abbreviate | omitted. The position acquisition unit 504 can be configured by, for example, an antenna for receiving radio waves from a satellite, a tuner that demodulates received radio waves, and an arithmetic circuit that calculates a current position based on demodulated information.

  As a radio wave from the GPS satellite, an L1 radio wave carrying a C / A (Coarse and Access) code and a navigation message with a carrier wave of 1.57542 GHz is used. Thereby, the current position (latitude and longitude) of the own apparatus is detected. In detecting the current position of the device itself, information collected by various sensors such as a vehicle speed sensor and a gyro sensor may be taken into consideration. A vehicle speed sensor detects from the output side shaft of the transmission of the vehicle carrying a navigation apparatus.

  In addition, when acquiring the current position of the device itself, information collected from various sensors such as an angular velocity sensor, a travel distance sensor, and an inclination sensor may be taken into consideration. The angular velocity sensor detects an angular velocity when the host vehicle rotates and outputs angular velocity information and relative orientation information. The travel distance sensor calculates the number of pulses per one rotation of the wheel by counting the number of pulses of a pulse signal with a predetermined period that is output with the rotation of the wheel, and travel distance information based on the number of pulses per one rotation Is output. The inclination sensor detects the inclination angle of the road surface and outputs inclination angle information.

And an A / D converter that performs A / D conversion.

  The communication unit 508 receives radio waves (television radio waves) including an electrical signal of a television program that is modulated by a television broadcasting station and transmitted on a high-frequency carrier wave. For this reason, the communication unit 508 includes an antenna for receiving a television wave that can resonate with the frequency of the television wave and induce a large current. In addition, the communication unit 508 includes a tuner for obtaining a specific frequency of television radio waves from the received radio waves. The TV radio wave obtained by the tuner is decomposed again into a carrier wave and an electric signal by audio detection and video detection. It should be noted that the configuration and operation related to the reception of the TV radio wave and the processing of the received TV radio wave are well-known techniques, and thus description thereof is omitted.

  For example, when weather information is received from the outside of the navigation device, the communication unit 508 may communicate with an external server or the like that stores various types of information in order to acquire weather information. Communication for acquiring weather information can be realized using various known wireless communication technologies. In the present embodiment, the configuration and communication technology for obtaining weather information are well-known technologies, and thus description thereof is omitted.

  The communication unit 508 may receive road traffic information such as traffic jams and traffic regulations regularly (or irregularly). The reception of the road traffic information by the communication unit 508 may be performed at the timing when the road traffic information is distributed from the VICS (Vehicle Information and Communication System) center, or the road traffic information is periodically requested from the VICS center. You may go on. The communication unit 508 can be realized as, for example, an FM tuner, a VICS / beacon receiver, and other communication devices. The received road traffic information is used, for example, for re-searching the route during route guidance.

  Detailed description is omitted because it is a well-known technology, but “VICS” means that road traffic information such as traffic jams and traffic regulations edited and processed at the VICS Center is sent in real time, and text / It is the information communication system displayed with a figure. As a method of transmitting road traffic information (VICS information) edited and processed in the VICS center to the car navigation device, there is a method of using “beacon” and “FM multiplex broadcasting” installed on each road. “Beacons” include “radio wave beacons” mainly used on expressways and “optical beacons” used on major general roads. When “FM multiplex broadcasting” is used, road traffic information in a wide area can be received. When using a “beacon”, it is possible to receive necessary road traffic information at a location where the vehicle is located, such as detailed information on the most recent road based on the vehicle location.

  The route search unit 509 is based on the current position acquired by the position acquisition unit 504, the destination input by the user, and the map information obtained from the recording medium 505 via the recording medium decoding unit 506. The optimal route from the current position to the destination is calculated. In the present embodiment, calculation of the optimum route from the current position to the destination performed by the route search unit 509 will be described as route search.

  The route searched by the route searching unit 509 includes a route searched again before the start of route guidance by the route guiding unit 510 and a route searched again during route guidance by the route guiding unit 510. The re-search is performed when the user intentionally changes the waypoint or the destination in addition to the case where a traffic jam occurs on the route being routed. In many cases, the re-searched route includes the intention of the user. For example, if a route that travels along the sea is searched after a route that travels along the mountain, it is likely that the user wants a route that travels along the sea rather than along the mountain. I can guess that. Information on the route searched by the route search unit 509 or the destination set in the route search may be stored in a storage unit (not shown) provided in a navigation device such as a ROM or RAM, for example.

  The route guidance unit 510 records the information related to the route searched by the route search unit 509, the road traffic information received by the communication unit 508, the information related to the current position acquired by the position acquisition unit 504, and the recording medium 505. Based on the map information obtained via the medium decoding unit 506, real-time route guidance information is generated.

  The guide sound generation unit 511 generates tone and voice information corresponding to the pattern. That is, based on the route guidance information generated by the route guidance unit 510, the virtual sound source corresponding to the guidance point is set and the voice guidance information is generated, and this is sent to the guidance sound output unit 507 via the central control unit 501. Output.

  The recording unit 513 records the television program received by the communication unit 508 on the recording medium 514. When HD is used as the recording medium 514, the recording unit 513 is an HD recorder. When a DVD is used as the recording medium 514, the recording unit 513 is a DVD recorder. Since this is a known technique, the description of the structure of the HD recorder and the DVD recorder, and the reservation recording mechanism of the TV program in the HD recorder and the DVD recorder will be omitted.

  In the recording medium 514, the television program received by the communication unit 508 is recorded by the recording unit 513. In the recording medium 514, the television program received by the communication unit 508 is recorded by the recording unit 513. The recording medium 514 stores information information related to the television program recorded by the recording unit 513 in a nonvolatile manner. In recording, video and audio information is recorded. The recording medium 514 is not limited to a disk medium such as HD or DVD, and for example, a semiconductor memory such as a flash memory or other various media can be used.

  The recording condition storage unit 515 stores various conditions set for the reserved recording. As various conditions set for the reserved recording, for example, “whether or not to consider time information and weather information when extracting a keyword used for determining a recorded program” is cited. The time information is information related to at least one of the date and time when the route is searched by the route search unit 509. The time information is information related to at least one of the date and time when the route searched by the route search unit 509 is moved by the moving means.

  The weather information is information regarding the weather when the route is searched by the route search unit 509. The weather information is information related to the weather when the route searched by the route search unit 509 is moved by the moving means. The time information and the weather information may be stored in a dedicated storage unit provided for storing the time information and the weather information. The time information and the weather information may be appropriately acquired from an external server or the like as necessary when extracting a keyword used for determining a recorded program. In the recording condition storage unit 515, as various other conditions set for reserved recording, a recording mode such as a standard recording mode or a long-time recording mode is set.

  The database holding unit 516 holds various databases such as a seasonal database (see FIGS. 10 and 11), a regional area database (see FIG. 12), and a name attribute database (see FIG. 13). The contents of various databases in the database holding unit 516 may be updated regularly (or irregularly), or may be held fixedly. Further, the contents of various databases in the database holding unit 516 are not limited to those fixedly held in the navigation device. For example, the contents of various databases may be held in a disk medium such as HD or DVD. In this case, the database holding unit 516 includes a disk medium such as an HD or a DVD and a disk drive device that can read information held in the disk medium.

(Processing procedure of navigation device)
Next, a processing procedure of the navigation device according to the embodiment of the present invention will be described. The processing of the navigation device according to the embodiment of the present invention is realized by appropriately executing each process of keyword generation, recording program reservation list creation, and program recording.

  FIG. 6 is a flowchart illustrating a processing procedure performed when generating a keyword. In the process shown in FIG. 6, first, it is determined whether or not a destination is set (step S601). If it is determined in step S601 that the destination is not set (step S601: No), it is determined whether there is a history of destinations set in the past (step S602). If it is determined that there is no destination history (step S602: No), the process returns to step S601. Hereinafter, the set destination and the destination acquired from the history will be described simply as “destination”.

  In step S601, when it is determined that the destination is set (step S601: Yes), or when it is determined that there is a history of the destination (step S602: Yes), from the timing information regarding this destination. A seasonal recording keyword is generated (step S603). In step S603, first, information on the date and time when the destination is set or the date and time when the route to the destination is moved is acquired as time information. Then, the seasonal recording keyword is generated by extracting the seasonal recording keyword corresponding to the date and time specified by the acquired time information from the seasonal database. Specifically, for example, if the date and time specified by the time information are a certain day in December, a seasonal recording keyword “winter” is generated. For example, if the date and time specified by the time information are a certain day in December, seasonal recording keywords such as “New Year's card” and “Ski” are generated.

  Next, a local area recording keyword is generated (step S604). In step S604, a regional area recording keyword corresponding to a regional area including the destination and the route to the destination is generated from the information about the destination and the information about the route to the destination. Specifically, for example, if the departure place is a certain place in Saitama Prefecture and the destination is a certain place in Tokyo, regional area keywords such as “Kanto”, “Saitama”, and “Tokyo” are generated.

  Subsequently, a name attribute recording keyword is generated (step S605). In step S605, for example, a name attribute recording keyword related to the name of the destination is generated. Specifically, for example, if the destination is “Tokyo Zoo” located in a certain place in Tokyo, the name attribute recording keyword is used for the names of animals kept in the zoo such as “Koala” and “Panda”. Generate as Various recording keywords generated by the processing from step S603 to step S605 in the present embodiment realize the keywords of the present invention.

  In the present embodiment, a case has been described in which time information is considered as in step S603 when generating various recording keywords. However, the present invention is not limited to this. It is also possible to generate a recording keyword in consideration of weather information instead of time information. For example, in step S603, if the weather on the day when the destination is set or the day of departure for that destination is “snow”, keywords related to snow such as “skiing” and “skating”. May be generated. In this case, a dedicated database for storing keywords generated based on weather information may be provided, and keywords associated with snow may be generated based on the database. For the time information and the weather information, it is possible to generate a recording keyword in consideration of both the time information and the weather information.

  FIG. 7 is a flowchart for explaining a processing procedure performed when a recorded program reservation list is created. The processing shown in FIG. 7 stands by until it is determined that the EPG program guide has been acquired (step S701: No). Although it is a well-known technique, the EPG program guide is sent using a gap between radio waves. For this reason, the acquisition of the EPG program guide in step S701 is performed, for example, at the timing when the EPG program guide is sent.

  If it is determined that the EPG program guide has been acquired (step S701: Yes), a recording keyword is extracted (step S702). In step S702, a recording keyword is extracted based on the seasonal recording keyword, the regional area recording keyword, and the name attribute recording keyword generated by the processing shown in FIG. For example, all of the generated seasonal recording keywords, regional area recording keywords, and name attribute recording keywords may be used as keywords.

  Next, it is determined whether or not there is a program including the extracted recording keyword in the EPG program guide (step S703). If it is determined that the program including the recording keyword is in the EPG program guide (step S703: Yes), a recorded program reservation list is prepared for recording the program by reservation (step S704). For example, when “autumn” and “Kanto” are extracted as recording keywords, a recorded program reservation list is created so as to record a program “the highlight of autumn leaves in Kanto”.

  If it is determined that the program containing the recording keyword is not in the EPG program guide (step S703: No), it is determined whether the recording keyword has been changed (step S705). If it is determined that the recording keyword has been changed (step S705: Yes), the process proceeds to step S702. If it is determined that the recording keyword has not been changed (step S705: No), the process ends.

  FIG. 8 is a flowchart for explaining a processing procedure performed when recording a program. In the process shown in FIG. 8, it is first determined whether or not there is a recorded program reservation list (step S801). If it is determined that there is a recorded program reservation list (step S801: Yes), it is determined whether the battery voltage is sufficient (step S802). In step S802, it is determined whether or not the battery voltage is sufficient by detecting the voltage value of the battery and determining whether or not the detected voltage value is greater than or equal to a predetermined value. If the detected voltage value is less than the predetermined value, it is determined that the battery voltage is insufficient.

  If it is determined that the battery voltage is sufficient (step S802: Yes), the program recording is started after waiting for the broadcast time of the program reserved for recording based on the recording program reservation list (step S803). Then, during program recording, the free space of the recording medium 514 is monitored to determine whether the free space of the recording medium is sufficient (step S804).

  If it is determined that the free space of the recording medium 514 is sufficient (step S804: Yes), the recording of the program is continued until the end of the program, and the process ends. On the other hand, when it is determined that the free space of the recording medium 514 is not sufficient (step S804: No), it is determined whether or not the program can be recorded by changing the recording mode (step S805).

  The change of the recording mode means, for example, a change from the standard recording mode giving priority to image quality to the long recording mode giving priority to extending the recording time, such as the 3 × recording mode. If it is determined that the program can be recorded by changing the recording mode (step S805: Yes), the recording mode is changed to the long-time recording mode (step S806), and the program recording is continued until the end of the program. To end the process. When it is determined that the recording of the program is impossible even by changing the recording mode (step S805: No), the recording mode is changed to the long-time recording mode and only the recordable amount is recorded (step S807). .

  In step S802, when it is determined that the battery voltage is not sufficient (step S802: No), a notification that the battery capacity is low is issued (step S808). The notification in step S808 is realized, for example, by transmitting a message for informing that the battery capacity is low to a preset address of the user's mobile phone. Accordingly, it is possible to reliably inform the user that the battery capacity is low. In addition, the notification in step S808 can be realized by, for example, a buzzer that generates a warning sound in response to an instruction from the navigation device.

  In recording a program, the process shown in FIG. 9 may be executed instead of the process shown in FIG. FIG. 9 is a flowchart for explaining another processing procedure performed when recording a program. In the process shown in FIG. 9, first, a reservation list and history information of the home recorder is acquired (step S901). An example of the home recorder is an HDD recorder. Then, it is determined whether there is a recorded program reservation list (step S902). If it is determined that there is a recorded program reservation list (step S902: Yes), the contents of the recorded program reservation list are modified to add information included in the reservation list and history list of the home recorder (step S903). .

  In step S903 of FIG. 9, “recorded program reservation list content addition correction” is described. On the other hand, when it is determined that there is no recorded program reservation list (step S902: No), a recorded program reservation list is newly created based on information included in the reservation list and history list of the home recorder (step S904). In step S904 of FIG. 9, “New recording program reservation list creation” is described.

  Next, it is determined whether or not the battery voltage is sufficient (step S905). In step S905, similarly to step S802, it is determined whether or not the battery voltage is sufficient.

  When it is determined that the battery voltage is sufficient (step S905: YES), the program waits for the airing time of the program reserved for recording based on the recorded program reservation list added or modified in step S903 or step S904. Then, program recording is started (step S906). Then, during program recording, the free space of the recording medium 514 is monitored to determine whether the free space of the recording medium 514 is sufficient (step S907). If it is determined that the free space of the recording medium 514 is sufficient (step S907: Yes), the program recording is continued until the end of the program as it is, and the process is terminated.

  On the other hand, when it is determined that the free space of the recording medium is not sufficient (step S907: No), or when it is determined that the battery voltage is not sufficient (step S905: No), it is included in the recorded program reservation list. The information to be transferred is transferred to the home recorder (step S908). In step S908 of FIG. 9, “transfer recorded program reservation list contents to home recorder” is described. The home recorder records a reserved program based on the data transferred from the navigation device. Since the home recorder and the program recording process in the home recorder are well-known techniques, description thereof will be omitted.

By recording a recorded program, it is possible to record a program that the user is interested in without requiring complicated operations such as specifying the broadcast date, broadcast time, broadcast channel, or keyword of the program to be recorded in advance. it can. In response to this, for example, when a historical site is a destination, the user can appropriately accumulate information on the historical site to deepen understanding and interest.

  A keyword for determining a program to be recorded is generated from information related to the destination or information related to the route based on the date and time when the route was searched or information related to the date and time when the moving means moved along the route. In this case, it is possible to record a program in consideration of the timing when the user's actual operation or action is performed.

  In addition, when a keyword that determines a program to be recorded is generated from information about a destination or information about a route based on information about the weather when the route is searched or information about the weather when the moving means moves along the route It is possible to record a program that takes into account the weather when the user's actual operation or action is performed.

  As a result, it is possible to record a program more relevant to the user's behavior and accompanying memories. Thus, according to the navigation apparatus of the present embodiment, it is possible to improve the entertainment property provided to the user.

  In the present embodiment, the case where the recording keyword is extracted in consideration of the time information and the weather information has been described.
